it ail whom it may concern.-

Be it known that I, BENJAMIN F. SWEET, a citizen of the United States, and a resident of Fond du Lac, in the county of Fond du Lac and State of Wisconsin, have invented anew and useful Improvement in Hubs for Vehicles and other Purposes, of which the following is a specification.

My invention relates to hubs both for large and small vehicles which may be used for various purposes and also for pulleys for shafting, for which they are well adapted. These hubs are more particularly designed for vehicle-wheels where great strength or unusual height is required-such as for portable engines, gun-carriages, army-wagons, automobiles, log-wagons, &c. 5 and one object of my invention is to make wheels of the knockdown order, whereby large or other wheels can after being entirely completed be taken apart and the hubs and boxes, spokes, fellies, and tires or rims (the fellies and tires or rims being made integral and in sections secured together with bolts) be packed in boxes of suitable size and shipped as freight at ordinary rates for freight that is not bulky.

My improvements are illustrated in the accompanying drawings, in which .Figure l is a side elevation of a hub einbodying my invention. Fig. 2 is a side elevation showing tl1e central hubportion' having spoke-sockets for T-iron and the tubular boltwhich enters into the construction of the hub screwed into one end of said central portion. Fig. 3 is a plan of the centralport-ion of the hub, showing spoke-socketsadapted for T-iron spokes. Fig. 4 is a plan of the central portion of the hub having wire spokes therein. Fig. 5 is a top view of the central portion of the hub fitted for wire spokes, one end of it having spokes held therein with a cone-frustum-shaped thimble or washer fragment. Fig. 6 is a top viewof the central hub portion having spoke-sockets extending entirely across said hub portion. Fig. 7 is a top view of a hub having spoke-sockets for angle-iron. Fig. 8 is an end View or plan of the central part of the'hub having spokesockets of rectangular form, similar to those in Fig. 1. Fig. 9 is a vertical section upon the line as 00 of Fig. 7 and showing the two tubular bolts, the central hub portion having a part of two angle-iron spokes upon the'up per side and a'spoke-socket in the lower side adapted for a spoke of angle-iron, the two cone-frustum-shaped thimbles or washers, and an ordinary axle-box fitted within the two tubular bolts, one of them showing the axlebox integral with the bolt and the other a removable box. Fig. 10 is a vertical section showing the two tubular bolts, the central hub portion, and an axlejournal bearing, one end being fitted with balls and the other with rollers. Figoll is an end view of the inner'end of one of the tubular bolts with the balls or rollers, upon a larger scale than in Fig. 10, arranged'the'rein, the thimble 'forretaining them in position being omitted. Fig.

12 is an end view of the inner end of one of vertical section of a central hub portion,

similar to the one in Fig. 13, through two of its spoke-sockets, one of them having the inner end of a spoke therein anda part of two other spokes being shown in position in the hubsection. Fig. 15 is an end view of an angleiron spoke for which the hubs in Figs; 7 and 9 are adapted. Fig. 16 is a fragment of the right-hand tubular bolt shown in Fig. 10 and showing a modification in the form of the ends of the rollers, of the roller-bearing, and of the sockets or seats in the tubular bolts and the retaining-thimbles for holding the rollers in position while revolving. Fig. 17 is an end viewof an oval-iron spoke adapted for use in the hub-sections shown in Figs. 4, 5, 13, and 14 by making a slight change in the form of-their spoke-sockets.

Similar numerals indicate like parts in the several views.

1 2, 1 2,1 2", and 2' indicate left and right hand tubular bolts, respectively; 3, the shoulder under the tubular-bolt head; 4., lugs upon the tubular-bolt heads; 5, threads upon the tubular bolts, which engage corresponding threads in the hub-sections; 6 6 6", central hub-sections; 6*, the central screwhole in the hub-sections; 6", the hub of section 6"; 7 7, shoulders on the central hubsections; 8 8' 8 8 8 8 spoke-sockets in the hub-sections 9, side sockets in spoke-sockets for receiving lips of spokes; 10, bolt or rivet holes in hub-sections; 11, oval-iron spokes; 12, wire spokes; 13, round-iron or pike spokes; 14, T-iron spokes; 15, angle-iron spokes; 16 16, lips upon spoke tenons; 17 17 17", thimbles or cone-frustum-shaped washers; 18 18, concave washers; 19, a shoulder upon a concave washer; 20, axle-box integral with tubular bolt; axle-box sections separate from tubular bolt; 21 21' 21", shoulders in the outer ends of the tubular bolts; 22, balls in the axle-box; 23 23, rollers in axle-box; 24 24' 24", thimbles for retaining balls and rollersrespectively in position; 25, shoulders within tubular bolts for preventing the entrance too far of the thimbles 24, 24, and 24 26, a compressible washer of leather or other suitable material; 27, bolts or rivets through thimble 17, the central hub-section, and thinnble 17; 28, screws through thimbles 17, 17, and 17".

As will be seen in the several figures, there are many forms of spokes for which this construction of hub is adapted, as wood spokes in Figs. 1, 6, and 8 and metallic spokes in Figs. 2, 3, 4, 5, 9, 13, and 14. The central hub-sections are intended to be made of cast metal and the central screw-hole and spokesockets formed in casting them. The hubsections are then to be bored and screwthreaded for receiving the tubular bolts. The bolt-holes 10 can be formed and the shoulders 7 7 or 19 turned 06 and the space outside of said shoulders faced up, if a fine finish is desired, or the shoulders and space can be left as cast, if desired.

For some forms of spokes instead of making the central part of a single piece it may be, as shown in Figs. 13 and 14, in three parts, the central part with a hub long enough to receive the threaded ends of the tubular bolts and two washers 18 and 18, one upon each end of the hub of the central part and between which the sockets for receiving the spokes are formed, they being formed wholly or partly in the central section, as the particular spoke to be used requires. This form of hub can be used with thimbles 17 17, as in Fig. 1, or with 17", as in Fig. 9, the former having bolts through thimbles and hub-sections and the latter without said bolts. The meeting surfaces of the central section and washers 18 18 can be made concave and convex, as shown, or the spoke-sockets can be formed for giving the necessary inclination to the spokes and said surfaces made'straight and the washers be a fiat disk.

The tubular bolts are threaded, bored, and fitted forthe axle, as shown in the right-hand end of Fig. 9, or provided with removable axle-boxes, as shown in the left-hand end of said figure, as may be desired. Each hub is intended to have its tubular bolts both with integral axle-journals, as in the right hand of Fig. 9, or both with removable axle-journals, as in the left-hand end of said figure. The sections 20 are to be carefully fitted for insertion into the bore of the tubular bolts, their entrance too far being prevented by the shoulders 21 and their bore having the necessary taper for the usual carriage-axle. If desired, the tubular bolts may be fitted for receiving balls, as in the left-hand end of Fig. 10, rollers, as in the right-hand end of said figure, or rollers of the form shown in Fig. 16. In either case seats are formed near the outer ends of the tubular bolts for receiving the particular form used. Both ends of the hub are intended to be provided with the same form of antifriction device, as balls or rollers, although that is not essential. The tubular bolts are provided with shoulders 25 for limiting the distance to which the thimbles 24, 24', or 24" can be inserted, so as to provide seats with ample room for balls or rollers to revolve within.

The rollers are made longer upon their axial line than upon their surface that comes in contact with the vehicle-axle, their ends being globular or cone-shaped in form, and both the balls and rollers are provided with seats in the tubular bolts and in the ball and roller retaining thimbles of a form corresponding with the form of the antifriction device which may be used.

The inner ends of the axle-box sections and of the ball or roller retaining thimbles, as:

shown in Figs. 9 and 10, should be turned 0% to the required length and flush with the inhand threads, so that they can be screwed up tightly against each other.

The tubular bolts are to be screwed into the hub-sections with a spanner engaged with the lug 4 and may be secured from turning backward and becoming loose by the insertion of a screw through the thimbles 17, 1'7, or 17.", as shown in Figs. 1 and 9. a f
